Title: Tape loading device
Inventor: OGAWA TOKUKADO
IPC: G11B15/61
Filed: 1984-10-26
Abstract: PURPOSE:To simplify the structure by engaging and detaching the tape guide block and tape guide transfer device at the bottom opening part of a cassette tape. CONSTITUTION:At the time of unloading, a tape guide block 27 is placed at the area surrounded by a bottom opening part 25 of a cassette and a tape 4 and separated from a tape guide transfer device 79. When the block 27 tries to move on a guide groove 48b in the left direction as shown in the figure, the block 27 can be move because the width of the groove is made narrower by a protrusion 29a than the protrusion 59 of transfer rack of the block 27, and because the block does not have enough power to push up the protrusion 29a. Also if it tries to move in the right direction, the block 27 is stopped by the collision with a drum fixing block 30. Therefore, at the unloading mode, the block 27 is forced to stay at the position of the guide 48b.

IPC: G06T1/00
Filed: 1990-08-28
Abstract: PURPOSE: To enable the emphasis of image by determining plural sensitive colors respectively related to the different combination of input colors in the manner of function, relating one of sensitive colors to the averaged picture element of respective groups and replacing the respective picture elements of respective groups with the picture element of the sensitive color. CONSTITUTION: A black picture element 42A and a white picture element 48A are selected and mixed. The black picture element 42A and the white picture element 48A are not colors closest to a desired 50% gray picture element 46A but just with two picture elements, proper average shadow can be provided. Namely, when images is white and black are arranged in the shape of grid board as shown in a picture element 36A, the rms noise is increased but since longitudinal and lateral directions are alternately arranged, all the noise are concentrated at the diagonal tip of spatial frequency band width as shown in a spatial frequency noise spectrum 38A. These tips have 1.414 (the squire root of 2) times the maximum frequencies generated by the device as horizontal and vertical resolutions. Thus, the eyes of an observer sense the desired 50% gray image and the emphasis of the image is enabled.

Title: Pallet loading device control method
Inventor: NAKANO YOJI
IPC: B65G57/03
Filed: 1991-08-12
Abstract: PURPOSE:To provide a correct moving/stop position with the elongation of an endless belt taken into account by subtracting inertial travel rotating speed for correction to control the rotating speed of motors, thereby preventing overrun caused by inertial force to allow a load holder to be stopped correctly into a control position, and computing the moving control motor rotating speed required to move the necessary moving distance using the control reference value. CONSTITUTION:Prior to the start of work, an article holder is moved to store the inertial travel rotating speed from the output of a stop signal to the complete stop of the article holder, and the inertial travel rotating speed is subtracted for correction from the moving control rotating speed computed at an arithmetic unit by the required moving distance to control the rotating speed of motors 1-3. Prior to the start of work, the article holder is moved also by the specified distance, and the rotating speed during that time is counted to compute the control reference value. Using this control reference value, the moving control rotating speed of the motors 1-3 is computed from the required moving distance for determination. As a result, the load holder can be always stopped correctly in a control predetermined position in a pallet loading device.

Abstract: PROBLEM TO BE SOLVED: To reduce defects in reproducing operation by limiting a frequency which means the recording inversion of encoded data and represents its succession below a specific number and limiting the frequency of the succession of the shortest recording mask when the encoded data after modulation are recorded on a signal recording medium below a specific frequency. SOLUTION: In this method every arbitrary (m)-bit data of input data is converted into (n) bits (n>m) as encoding units according to a specific conversion table. The frequency of the succession of '1' meaning the recording inversion of the encoded data is limited to the specific number N which is between 2 and (n) and when the encoded data after modulation are recorded on a signal recording medium, the frequency of the succession of the shortest recording mark is limited below the specific number. When a signal is recorded and reproduced by using '8-9 modulation', the frequency of the succesion of '1' is limited to 3 and when it is recorded on a magnetooptic disk, only up to two shortest recording marks are allowed to succeed.

The thermal spraying layer 2' is now taken off with its solidification after melting it by heating uniformly over the whole length of whole periphery by a heating source 71 and the core metal 4 is removed with the ground layer 3 by machining. The pipe 1 coating the inner face with an elaborate lining layer 2 is thus formed.

Title: Semiconductor laser element
Inventor: YOSHIOKA YOSHIFUMI
IPC: H01S5/00
Filed: 1989-09-01
Abstract: PURPOSE:To achieve an easy fabrication and secure sufficient element characteristics by forming an activation layer where a well layer consisting of ZnTe and a barrier layer consisting of Al GaInP compound are alternately laminated and by making the composition ratio of the well layer to be the same as that of a Pn both clad layers. CONSTITUTION:An n-type (AxGa1-x)yIn1-yP is allowed to grow on the surface of an n-type GaAs substrate 2 for forming an n-type clad layer 3. Then, ZnTe which is an well layer 7 and (AlxGa1-x)yIn1-yP which is a barrier layer 8 are alternately multiple-laminated for forming an activation layer 5. Since ZnTe and (AlxGa1-x)yIn1-yP are in the same crystal structure, the well layer 7 and the barrier layer 8 which are alternately multiple-laminated form a distortion ultra grid and become the activation layer 5 in a multiple quantum well structure. Further, a P-type (AlxGa1-x)yIn1-yP is allowed to grow on the activation layer 5 for forming a P-type clad layer 4. Then, finally, a P-type GaAs layer 6 is subjected to crystal growth, thus eliminating such a troublesome work as controlling the composition ratio of an element accurately for each composition ratio on fabrication.
